Perry,
TPL9201 has it's own internal voltage regulator so a higher voltage supply is needed for the VIN pin.
TPL9201 has no serial output so chaining devices is not possible.
Other Parts Discussed in Thread: TPL9201 The TPL9201 relay driver has a serial bus for programming it comprising the usual SCLK (serial_clock), MOSI (serial data) and NCS (chip_select_bar) pins.
We are trying to drive two of these chips as well as other…
Other Parts Discussed in Thread: TPL9201 Is it allowed to connect Thermal Pad to GND plane ?
In datasheet http://www.ti.com/lit/ds/symlink/tpl9201.pdf , Page 8, Figure 1. Serial Communications , you shall add a new line which would describe an update…
Other Parts Discussed in Thread: TPL9201 I'm using the TPL9201 relay driver, and they don't respond at all. I've got 12V input on pin 19, 5V out on pin 18 and 6.5V out on pin 13 (a no-connect). RST on pin 14 is floating, but with a pull up to 5V it goes…
I would love to know if anybody has successfully interfaced the TPL9201.
I have not been able to make it work.
I have a test program that drives ot from the PC parallel port, so I can play with the serial port waveforms.
With waveforms exactly…

We are planning to
use the TPL9201 as a relay driver. If we are not using the 5V regulator or sync
features, can we leave SYN, ZVS,5VOUT,RST,RDELAY and EN1 disconnected?
Part Number: TMCS1101 Other Parts Discussed in Thread: TPL9201 Tool/software: Hello, I'm having an issue with the TMCS1101A4B and kindly ask for help. I power on a 230V 0.5A motor by switching on a relay and then measure the current with the TMCS1101…
Hi KPK,
I'm going to try to move this thread to another forum in hope someone from the right product group at TI can chime in with some guidance. I did notice that there are several multi-channel relay drivers listed in this product category: www.ti…
Loren,
There is production savings for 16 pins packages over 18. Also the ULN2003 is more popular than ULN2803. 8 channels may come but I don't have a time table. Perhaps the extra channels can be used as logic inverters or open collector NAND gate…
Mohd,
That data is available on the product page in the Quality & Environmental Data section. http://www.ti.com/product/ULN2803A The worst case VCE(SAT) is 1.4V (per data sheet). With 250mA, that is 350mW per channel. With a package TJA of 73C/W, the…
